Specification of Letters Patent. p t t A p; pm

dpplieatlon' filcd March 16,1917. Serial No. 155.1%.

To all whom it may concern.

wmswoaee' -a. citizen ofthe United States,- and resident of the borough of Brooklyn,

county of Kings, city and State of New York, have invented certain new and useful Improvements in Radiator-Caps, of which the following is a specification. By the termradiator I refer more particularly. to theradia'tors of automobiles and so that my device may be fully understood and appreciated I will first describe the ordinary and well-known construction.

lEach radiator isxfitted with a vscrew threaded nozzle through which water is introduced into the radiator and upon the screw threads of the nozzle aca is placed which must'be entirely remove .when the radiatorlis to be filled.

Owing to; the expansion and contraction it is sometimes quite-difficult to remove the radiator cap and particularly if the cap has been screwed down tight when the radiator is cold and. therefore many automobile drivers allow the cap to remain partially insecure with'the result that radiator ca s are ofttimes lost or, because they must e entdirely removed, they are very Often mislai I To overcome the inconveniences due to the 'misplacement or loss off'a radiator cap ll have devised the construction which I will now describe, which has for its purpose a-' cap or'lclosure for radiators that will always remainin position and will automatically retain aclosed position when not deliberaftely-secured open;

' y ."ll-he following is what ll consider a good means of carryingout my invention and the accompanying drawing should be referred to for a complete understanding of the specification which follows.

In the drawing I Fire 1 shows a partlal sectlonal view of device.

m hig. 2 an elevation thereof.

Fig. 3 a plan view. t Fig. 4L a plan view'of apart removed. I Similar "reference numerals indicate like parts in-alldfthe figures where theyapear. 1p As in the use of m device itis not necessary to modify or c ange the construction of the radiator ll have not shown a complete rad but r the ew P n In the drawing the radiator as a whole is in I but in the drawing llz-s'how merely a semicircumferential liparranged at one side of the member 3. Within the lip is a flange 6, .T

formedintegral with the member 3or secureolthereto, andaat the side of the flange opposite the highest part of the lip 3 T provide-bearings if, for a shaft 8, and formed integral withfthe bearings is an upwardly or outwardly extending resilient member 9,

which maybe termed afpost. Upon-the.

post 9, ll arrange a hook 10 for a that shall appear later.

Rotatable upon the shaft 8, is a disk .11, having an upwardly or outwardly projecting portion 12. The portion 12 passes purpose through the center perforation of the flange 6, andthe disk ll, projecting-beyond the .portion 12, finds a bearing upon the inner side of the ring 6.

Formed integral with the disk 11 or secured therein is an operating handle or lever 13, projecting lbeyond the side of the member 3.

Upon the shaft 8 I arrange a spring 14L as shown in Fig. 4, and the-center elongated loop 15, of" the spring, hears upon the under side. ofthe member 11, at a-point heyond the center thereof. The spring 14-15 urges the disk llupward'and Outward so that under normal conditions and underthe infiuence of the s ring the disk llwill hear in 1" and relia lymponthe fiange 6.

To secure my ,-.dcvice upon the screw threads of the nipple 2, ll provide a set screw 16, but asit will probably not he necessary to remove my device it will he understood that it may be secured to the nipple 2by=soldering or brazing, or the cylindrical member 3 'ma be permanently securcd to the radiator wlthout the use of-the nipple 2. From the description of my device it will be seen that'the passage into the radiator is normally closed. When it is desired to introdhuce wa into the rater, the lever ioo 1a is lifted, this will force inward and downward the disk 11 and part 12, compressing the spring 15 or partially rotating it in a manner well understood with springs 5 of this character. The lever 13' is then engaged upon the hook 10, and water may be introduced into the radiator by'being poured over the lip 5.

When the radiator is filled to the proper 1 point the lever 13 is disengaged and the spring will automatically return the disk 11 and projection 12 into the position shown, thus closing the passage'of the radiator.

Parts may be used without the whole, the

15 loop 5 may be omitted, the projecting portion v12 may be omitted or may be substitut'ed' for by a decorative member, other modifications as to shape and size may be made within the scope of the appended claims without departing from the principle or sacrificing the advantages of the invention. A

I see no reason why the whole device could not be made on a cone or funnel shape, the

upper portion being larger than the lower may materially assist in the introduction of water into the radiator.

Having carefully and fully described my invention what I claim and desire to secure by Letters Patent is:

l. A. device of the character described comprising a cylindrical member having screw threads at one end and an inwardly projecting flange at the other end, means interior of said cylindrical member for closing the passage through said flange, a double coiled spring for urging said closing means into a closed position, means for opening said closing means and means formed integral with said flange and cooperating with said closing means for retaining said closing means in an open position.

2. A device of the character described comprising a cylindrical member, an inwardly projecting flange formed integral therewith, a plurality of bearings in said flange, a shaft through said bearings, a disk rotatable on said shaft, a spring having a plurality of coils upon said shaft for r0- tating said disk upon said flange, a lever formed integralwith said disk for rotating said disk and means secured to said flange cooperating with said lever for retaining said disk in an open position.

Signed at New York city, count Stage of New York this 10 day of 191 and arch,

WILLIAM HENRY WADSWORTH.
